The Reds youngster added another two assists to his tally this season as Liverpool overcame a scare and came from behind to beat West Ham at Anfield.
Alexander-Arnold dug out a cross for the Reds opener inside the opening ten minutes as Gini Wijnaldum directed the ball into the back of the net. However, Issa Diop levelled for the visitors minutes later, before Pablo Fornals put the visitors 2-1 up after the break.
With a little under ten minutes remaining, Alexander-Arnold was alive to the situation as Joe Gomez's left-footed strike took a deflection and fell his way. The 21-year-old got to the ball ahead of Fabianski and prodded it towards Sadio Mane, who finished home with ease to seal the win for the Reds.
Speaking on Sky Sports' Monday Night Football after the game, Alexander-Arnold said: “We felt like we've dominated the game but it's football and we've let them have two chances.
“They've scored off a set-piece, the set-pieces were probably their best chances of scoring today so we need to look at that. But we've dominated the game, tried to create as many chances as possible. We're happy with the win, that's the main thing, but there's a lot of things we need to get right.”
On the support at Anfield, he said: “Obviously the fans were unbelievable. They were massively with us - especially when we were behind or conceded a goal - so for us, it's a massive help to have the fans like that.
“It's rare that a team can concede a goal and their fans are up and they were trying to motivate us, and that makes us go even more.
“For us, we just tried to keep going, that's the mindset that's been drilled into us by the manager. We just need to keep going and keep going and it paid off in the end.”
Alexander-Arnold now has 12 assists in the Premier League, and 14 in all competitions, as he leads his teammates in the assists charts.
Whilst he put in a disappointing showing, for his standards, away to Atletico Madrid last week, his ability to influence games from the right and be one of the Reds' most threatening players was clearly on display once again.
When asked whether he aims for the player or a particular area when winding up his crosses, he said: “A bit of both.
“I think sometimes when you get the ball and you're thinking about crossing it then you have to look in and see if anyone's in the box and see where the runs are going to be made, and then it's about hitting areas really, saying to the attackers: ‘Go and attack it.'
“That's what I tried to do today, I tried to put balls into the box and when you're getting space out wide and you've got a little bit of time it's always good to get the ball out of your feet and try to cross it, but I'm doing whatever I can to help the team and that's how we all think.”
